As shown in FIG. 2A, in the embodiment, the user may operate a laser light source 260 to generate a laser beam, and the laser beam from the laser light source 260 may pass through the second hole 231 of the second insulation layer 230 and the first hole 221 of the first insulation layer 220 to the signal line 210, so as to perform a laser cutting or a laser welding on the signal line 210. The detailed description is as follows.

Please refer to FIG. 4 . The signal line 210 may be the data line DL and electrically connected to the light-emitting unit LD. When a defect occurs in a position 410 of the data line DL, a cutting may be performed at a position 420 and a position 430 of two sides of the defect position 410 on the data line DL. The cause of the defect may, for example, be damage caused by a particle or an electrostatic discharge. The repairing structure 200 described in the disclosure may be adopted for use in at least one of the cutting position 420 and the cutting position 430.

Please refer to FIG. 2B and FIG. 4 at the same time. The laser cutting may be performed on the signal line 210. Specifically, a manner of laser cutting may be used at least one of the cutting position 420 and the cutting position 430 on the signal line 210 (data line DL) to obtain the repairing structure 200 shown in FIG. 2B. According to other embodiments, the signal line 210 may be the gate line GL or the emission signal line EML, but the disclosure is not limited thereto. As shown in FIG. 2B, when the laser beam is used to perform the laser cutting, the part of the signal line 210 that overlaps the position of the laser light source 260 may be cut by the laser light source 260. Specifically, the laser beam generated by the laser light source 260 may pass through the second hole 231 of the second insulation layer 230 and the first hole 221 of the first insulation layer 220 to the signal line 210, so that the signal line 210 is melted and cut by the laser light source 260, and a cutting portion 211 is formed inside the signal line 210, achieving the effect of signal isolation.

Please refer to FIG. 2C and FIG. 4 at the same time. The laser welding may be performed on the signal line 210. Specifically, a manner of laser welding may be used at least one of the welding position 440 and the welding position 450 on the signal line 210 (data line DL) to obtain the repairing structure 200 shown in FIG. 2C. As shown in FIG. 2C, when the laser beam is used to perform the laser welding, the part 212 of the signal line 210 that overlaps the position of the laser light source 260 may be melted by the laser light source 260. Specifically, the laser beam generated by the laser light source 260 may pass through the second hole 231 of the second insulation layer 230 and the first hole 221 of the first insulation layer 220, so that the part of the fifth insulating layer 270 that overlaps the position of the laser light source 260 is cut by the laser light source 260 and a gap 271 is formed inside the fifth insulating layer 270, and the part of the signal line 210 is melted and drops along the sidewall formed by the gap 271 of the fifth insulating layer 270 and onto the repairing line 280. Accordingly, the melted signal line 210 may be formed inside the gap 271 to serve as a connection portion 210C, so that the signal line 210 may be connected to the repairing line 280 through the connection portion 210C to generate an electrical connection. Then, the signal transmitted by the signal line 210 may be transmitted by the repairing line 280, thereby repairing the signal. Therefore, the design of the repairing structure 200 is simple, or the repairing time may be decreased, increasing the convenience of use. In some embodiments, the connection portion 210C may at least partially overlap at least one of the first hole 221 and the second hole 231, but the disclosure is not limited thereto.

According to some embodiments, please refer to FIG. 4 , the signal line 210 (data line DL) may include the laser cutting position 420 and the laser welding position 440 at the same time. Specifically, in the electronic device 100, the first insulation layer 220 may include a first hole 221C (as shown in FIG. 2C) and another first hole 221B (as shown in FIG. 2B), and the second insulation layer 230 may include a second hole 231C (as shown in FIG. 2C) and another second hole 231B (as shown in FIG. 2B). The other first hole 221B and the other second hole 231C at least partially overlap. As shown in FIG. 2C, the laser welding may be performed in a position that overlaps at least one of the first hole 221C and the second hole 231C, so that the signal line 210 may be electrically connected to the repairing line 280 through the connection portion 210C. As shown in FIG. 2B, the laser cutting may be performed in a position that overlaps at least one of the other first hole 221B and the other second hole 231B, so as to form the cutting portion 211 of the signal line 210. The cutting portion 211 at least partially overlaps at least one of the other first hole 221B and the other second hole 231B.

In some embodiments, the width D1 of the first hole 221 of the first insulation layer 220 or the width D2 of the second hole 231 of the second insulation layer 230 may be greater than the width of the size of the laser beam from the laser light source. Accordingly, the laser cutting or the laser welding may be performed easily. For example, when the laser beam emitted by the laser light source 260 is used to perform the laser cutting on the signal line 210, the design of the width of the above holes may allow space for metal splashing. In addition, the size of the laser beam from the laser light source 260 may be 3 micrometers*3 micrometers, but the disclosure is not limited thereto. For example, the width D1 of the first hole 221 of the first insulation layer 220 or the width D2 of the second hole 231 of the second insulation layer 230 may be greater than 3 micrometers, but the disclosure is not limited thereto.

Furthermore, the third insulation layer 240 is disposed between the signal line 210 and the first insulation layer 220, and a part of the insulation layer 240 may be exposed in the first hole 221 of the first insulation layer 220.
